It’s common for sawmills to utilize sprinkler systems to keep logs moist and prevent them from drying out too quickly. This is important because when logs dry out too fast, they can develop cracks at the ends due to the sudden reduction in moisture content. By keeping the logs wet, sawmills can avoid this issue and ensure that the logs are in good condition for processing.
Why do they wet logs of wood?
Storing logs in water has several benefits that can help improve the quality of the wood and reduce risks associated with handling them. Firstly, it minimizes the risk of fire, which is especially important in dry and hot climates. Secondly, it washes away dirt and debris that could dull saws and other cutting tools, ensuring that the wood is clean and ready for processing. Finally, it prevents splitting of logs that might otherwise dry out before they can be milled, which can lead to lower quality wood and wasted resources.
To achieve this, cargo mills often use a system of floating log booms to contain the logs from delivery until they are ready to be processed.
Should logs be milled wet or dry?
Summary: To ensure proper drying of logs, it is important to mill them as soon as possible after they are felled and to seal the ends immediately. This will prevent the logs from absorbing moisture and developing mold or rot. By taking these steps, you can ensure that your logs are properly dried and ready for use in construction or other projects.
How long do logs need to dry before milling?
When it comes to drying lumber, patience is key. After cutting your logs, it’s important to let the wood air-dry for an appropriate amount of time. A general guideline is to allow one year of drying for every inch of board thickness. To ensure that your lumber is properly dried, it’s recommended to invest in a moisture meter to check its moisture content.
Kiln-dried lumber, which is dried in a controlled environment, typically has a moisture content of around seven percent.
Why do lumber mills keep wood wet before processing?
It’s common for sawmills to utilize sprinkler systems to keep logs moist and prevent them from drying out too quickly. This is important because when logs dry out too fast, they can develop cracks at the ends due to the sudden change in moisture content. By keeping the logs wet, sawmills can avoid this issue and ensure that the logs are in good condition for processing.
How long can logs sit before sawing?
It’s best to saw logs as soon as possible without waiting for any particular reason. However, some logs may sit for a few weeks or even months before being sawn. To ensure proper air circulation, reduce dirt in the logs, and make it easier to move them, it’s recommended to stack them on a pair of sacrificial logs. This will help keep the logs in good condition and make the sawing process smoother.
How do you know if logs are dry enough?
“`If you’re looking for well-seasoned wood, examining the ends of the logs is key. Dry seasoned wood will have dark, cracked ends, while wet wood will be heavier and lack the hollow sound that comes from two pieces of dry wood hitting together. If you see any green color or find it difficult to peel off the bark, the log is not yet dry and should be left to season further.“`
Can you burn logs straight away?
The design of the fire box and air flow controls is optimized to maximize the efficiency of burning woodfuel with a moisture content of 20% or less. It’s important to note that green or freshly felled logs should not be used in a domestic stove or open fire until they have been properly dried to a moisture content of 20% or less. This ensures that the wood burns efficiently and produces less smoke and pollutants.
Is it better to mill logs green or dry?
“`When it comes to cutting logs, opting for green ones can give you more control over the splitting process. This is because logs that have already started to dry out are more likely to have already begun splitting or are building up stresses that will eventually lead to splitting. Therefore, it’s best to saw your logs as soon as possible after they’ve been cut down. Interestingly, green wood is also easier to cut than dry wood, making the process smoother and more efficient.

What length logs do sawmills want?
“`When it comes to sawmills, the most common lengths are 12′ (12’6”) and 16′ (16’6”). However, the question of how small is too small for your mill depends on your specific needs. As a sawmill operator, I can mill logs down to toothpicks if that’s what you want. But the real consideration is whether or not it’s cost-effective for you.
So, it’s important to assess your requirements and determine the optimal size for your milling needs.“`
How do you make logs dry faster?
If you’re looking to dry firewood quickly, there are a few things you can do to speed up the process. First, remove the bark from the wood and stack it in a way that allows air to circulate around it from all sides. This will help the wood dry out more quickly. If it’s raining outside, you can cover the top of the woodpile to keep rain from getting in.
However, it’s important not to cover the sides of the woodpile, as this can prevent water from evaporating from the ends of the wood and slow down the drying process.
Can logs be too dry?
Yes, it is true that dry timber can easily catch fire and burn rapidly, consuming a significant amount of air and leading to higher levels of particulate emissions. However, it is important to strike a balance when it comes to the moisture content of wood used for burning. Surprisingly, a small amount of water, around 12-20%, can actually be beneficial for wood burning. This helps to ensure that the wood burns efficiently and produces less smoke and pollutants.

How long should you dry logs for?
“`The seasoning process of wood varies depending on the type of wood. Softwood can be dried in as little as 6 months if the process is done correctly. However, hardwood, like oak, can take anywhere from 1 to 2 years to season properly.“`
Does wood have to dry before milling?
It’s important to note that lumber doesn’t dry effectively while still in log form. The drying process only occurs once the logs have been milled into boards. Therefore, it’s best to leave your logs standing as trees until you’re ready to use them. Once you’re ready, it’s important to mill and sticker them quickly to ensure proper drying.
However, if you’re looking to create spalted lumber, you’ll need to let the logs sit for a while, typically through at least one hot summer.
Is it better to mill logs green or dry?
“`When it comes to controlling splitting, cutting logs while they are still green is the way to go. If you wait until the logs have started to dry, they may already be showing signs of splitting or developing stresses that will eventually cause them to split. That’s why it’s best to saw your logs as soon as possible after they’ve been cut. Interestingly, green wood is also easier to cut than dry wood, making the process even smoother.
